Title: Improvements in automatic circuit breakers
IPC: H01H71/50
Filed: 1934-06-12
Abstract: 420,653. Automatic circuit-breakers; snap-action switches. SHEVLIN, J. T., 15, South Street, Finsbury, London. June 12, 1934, No. 17402. [Class 38 (v)] In a push-button switch with automatic release provided with two contact-members 3, 5 in the same circuit, the circuit being made by the member 5 and broken by the member 3, a spring 14 is stressed, preferably through toggle links 10, 11, on depressing the button 1, and serves to impart a sudden movement to the member 5 in the switching-in operation and a sudden movement to the member 3 in the switching-out operation, which movements cannot be retarded by the push-button. The spring 14 surrounds a rod 15 carrying the contact-member 5, and is placed in compression, on depressing the push-button 1, by a member 13 to which the toggle lever 11 is pivoted. The member 13 is secured to a slide 2 carrying the contact-member 3, which is moved into the circuit-closing position on depressing the button, but a rod 8 carried by the button extends through an opening in an extension of the rod 15 and prevents movement of the latter. On releasing the button, the rod 15 is freed and the contact member 5 is moved into engagement with the fixed contacts 6 by the spring 14. As long as the circuit remains closed, further operation of the push-button 1 is prevented by the extension of the rod 15. When the toggle is upset by the energization of an electromagnet 17 which attracts an armature 16, the circuit is rapidly opened at the contact-member 3 by the action of the spring 14, and the contact-member 5 is subsequently moved into the open position by the engagement of the member 13 with an abutment on the rod 15. A second pushbutton may be provided for actuating the armature 16 when it is desired to release the switch by hand. The switch is particularly adapted for tariff supervision. In the arrangement shown in Fig. 6, the release coil 17 is switched in by a thermostat 19 in the circuit to be controlled, and variations in the surrounding temperature are compensated by providing a co-operating contact on another thermostat 20, the distance apart of the contacts on the two thermostats being adjusted by a screw 21 for determining the value of the current at which the switch is opened. An additional thermostat may be provided to close a preliminary alarm circuit before the switch is opened. In the arrangement shown in Fig. 10, the circuit of an alarm device 31 is closed through thermostats 20, 40. This circuit includes a heating coil 42 surrounding another thermostat 41 which is adapted to close the circuit of the release coil 17 after an interval.

The torque controlled locking means for locking the slow pitch thread of the screw member of the device of the parent Specification comprises a cammed collar 20 mounted on the screwed member 7 the collar having a cam surface engaging a similarly shaped cam surface 19 on the operating member 13, a spring being provided between the cammed collar and screw thread whereby relative rotation of the two slow pitch thread elements 17, 18 is prevented until the longitudinal force produced by the torque applied to the operating member is sufficient to force the cammed collar longitudinally along the screw thread. As shown a compression spring 22 is provided between the inner end of the cammed collar 20 and an annular shoulder 21 on the spindle 7. Rotation between the collar and spindle is prevented by providing a slot 23 in the spindle and an inwardly projecting peg 24 on the collar. In a modification the collar rides on longitudinal splines on the spindle. Means may be provided to ensure the resetting of the thread 18 to the normally indexed operation of the operating member 13. On initial rotation of the member 13 the spindle 7 and member 13 rotate conjointly. On resistance being encountered by the sliding jaw, the member 13 commences to rotate with respect to the spindle whereupon the slow pitch thread 18 comes into operation.
